Rear Projection Television Lights?
I have an old 46" LXI rear projection television and the green light keeps turning off. How do I fix it? Also is there any online manuals or directions?

Green light turns off is usually just bad solder on the CRT board….resolder it.
If it still acts up, then measure the HEATER AC on the CRT, the 200 V supply, make sure the Cathode is running at 160V to 180V and the Screen voltage is around 300V….that will isolate the problem.

You won’t find any manuals online unless you want to pay for them and they do not include any instructions for fixing the TV. It is probably a power supply or sweep problem but there is no one standard way to fix it. Different things break so someone has to figure out which parts are bad and then replace them.
